ANTI'SKI'D DEVICE,

Application filed June 19,'1923. Serial No. 646,320.

tain new and useful Improvements in Antiskid Devices,`,of which the following is a` specification.

l\ly invention relates to anti-skid devices and is particularly adapted for use'on automobile wheels. The objects are to provide anti-skid means which may be applied to a. wheelwithout-jacking it up or moving the automobile so that the wheels will move onto the antiskid 1neans; andanti-skidv means whichr may be fitted tightly around'v thc .tireV of a wheel, thus preventing loose chains from dangling from the wheel and.i

striking the fenders and which are simple, durable and easlly manufactured. v

These ob]ects, and other advantageous ends which will be described'hereiuafte'n' Iv attain in qthe following manner, reference being had to the accompanying drawing in which l 1- Figure l is a side view of an automobile wheel having my-l invention applied thereto,

Figure 2 is an enlarged fragmentary I section on line 2 2 ofV Figure 1,

Figure 3 is a side view of a chain yholder which forms a part of my invention, and

Figure 4 1s a'perspectlve view of a modified form of'. rim which may be used with my invention. v

Referring to the drawing, l indicates the felloe of a wheel, Q-the rim secured to the felloemin any well known manner andy 3 the tire mounted on the rim.

My, invention includes lugs 4 secured to the opposite sides ofthe rim by rivets 5, or otherwis.f The lugs have holes 6 through which pass threaded stems 7' integral with chain holders 8. Nuts 9 on the threaded stemssecure the chain holders to the lugs.

The chain holders 8 varepreferably Hat and J v arcuate in shape as shown in Figures 2 and lers through the holes 11.`

3 and may be of any suitable length.

`of a llength suitable for three chains 10 `spaced apart and secured tothe chain hold- If the chain holders are comparatively lon and are provided with a; great number o chains, more stems may be provided on the chain holders to properly securev them to the lugs.

to tighten the chains, which embracey the In Figure 4 I have sho'wn the lugs 4, with holes 6'n1 therein, struck out from the sides of the rim 2?. In all other respects the rim is similar-dn construction to the rim shown in Figures l and 2. l y

To apply my improved anti-skid device to an autoniobilevwheel the stems on the chain. holders are passed through the holes in the lugs at opposite sides of the wheel so that the chains will embrace the. tire. 4The 65 I nuts are screwed on the stems until they engage the lugs and tightened slightly so the chains embracing lthe vtire are notl loose or liable to dangle. The nut is locked in this position by any suitable means such as the loclr` washer 1'2.

Myanti-skid device is of special advan- 'tage-when the automobile is stuck in mud er snow as itmay be applied without jacking t up the wheel or moving the automobile so 75 the wheel' will. run onto the device which was the common practice. The threaded stem on the cha-in holders makes it possible i,

tire. to any desired degree. When the first chain engages the ground and is strained it tends to cant one end of the ,chain holders. The last chain, which isnot engaging the ground and is connected to the. other end of the chain holders, tends 86 .to prevent the first end from canting. In( other words, the first chain is prevented, from slipping by the last chain and the last chain by the first chain. r

While 'I have described my invention as ce taking a particular form, itwill be understood that the various parts of my `inven- 4 tion may be changed v without departing fom the spirit thereof, and hence I donot limit myself to the precise construction set forth, but consider that 4 am at liberty to make such changes andalterations as fairly come within the scope ofthe appended claims. A

Having thus described my invention, leo what I claim as new and desire to secure by x vLetters Patent is In the form shown the chain holders are' 1. An anti-skid device for a wheel including a pair of chain holders; spaced chains connecting the chain holders; a stem extending-fromeach chain holder and disposed substantially midway between the. most) remote chains, and means forladjustably securing the stein to the wheel. v f2.
